Compliance Phase-Out: Traditional materials contain plastics (e.g. PE extrusion coating) or PFAS (fluorochemicals), facing increasingly strict global plastic restriction laws and health reviews.
Performance Pain Points: Packaging struggles to balance complex physical demands like grease leakage, waterproof softening, or moisture-proof caking.
Machine Adoption Barrier: Urgent need for paper-based alternatives that can run smoothly on existing packaging machines (must have excellent heat-sealability).
